WebJan 16, 2024 · Surface area of a cylinder formula. The formula for the surface area of a cylinder is: A=2\pi rh+2\pi {r}^ {2} A = 2πrh + 2πr2. In this formula, a, is the total surface area, r is the radius of the circles at both ends, h is the height, and π is the irrational number that we simplify and shorten to 3.141595, or even shorter, 3.14. WebNote that the radius is simply half the diameter. The formula for the volume of a cylinder is: V = Π x r^2 x h. "Volume equals pi times radius squared times height." Now you can solve for the radius: V = Π x r^2 x h <-- Divide both sides by Π x h to get: V / (Π x h) = r^2 <-- Square root both sides to get:
